摘要：HCN (hydrocyanic acid) and NH3 (ammonia) (including HNCO (isocyanic acid)) released during rapid pyrolysis of three biomass samples (rice straw, chinar leaves, pine sawdust) and a nitrogen rich material (soybean cake) were measured The pyrolysis runs were conducted at 600-1200 degrees C using a high frequency furnace Much more HCN than NH3 was released in the biomass runs while the reverse was observed in the soybean cake runs Because lignin was a common constituent of biomass cells and nearly absent in soybean, the effect of its content on HCN release from the biomass was determined A strong correlation was established for each biomass sample suggesting that lignin may promote formation of heterocyclic nitrogenous compounds which then decompose to form HCN HCN release and char/tar N formation decreased at a higher pyrolysis temperature Pyrolysis at > 1000 degrees C is desirable since most nitrogen in the biomass will be converted to N-2 with < 7% released as HCN and NH3
